Application filed August 27, 1926.

My invention relates to improvements in liquid feeding devices and more particularly to a device adapted to deliver oil or other liquid lubricant in small quantities to parts 01 a machine to be lubricated when the parts are set in motion .and automatically moved out of operation when the partscome to rest. One of the objects is to provide a device having an oscillating member which is moved by a fluid actuated means (not shown) connected therewith. 1

Another object is to provide a device having an oscillating member which operates by gravity to automatically move the member out of operation when the fluid actuated means is inert.

Another object is to provide an oscillating member having a wick or other capillary means which feeds oil from a reservoir when the member is moved to its operative position.

Another object is to provide certain improvements in the form, construction and arrangement of the elements whereby the above named and other objects may be of fectively attained.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents a plan view of myimproved device having the cover thereof broken away to show other parts more clearly.

Fig. 2 represents a detailvertical section taken in the plane of the line II-II of Fig. 1, looking in the direction of the arrows.

Fig; 3 represents a vertical section taken in the plane of the line IIIIII of Fig. 1, looking in the direction of the arrows, with the elements shown therein at rest.

Fig. 1 represents a similar View with the elements in an operative position.

Fig. 5 represents a vertical sectiontaken in the plane of the line V-V of Fig. 3, looking in the direction of the arrows.

Fig. 6 represents a vertical section taken in the plane of the line VIVI of Fig. 4:, looking in the direction of the arrows.

The device comprises a body 1 having a reservoir 2 therein and a cover 3 hinged at 4; to lugs 5, carried by the body 1. Mounted on the bottom 6 of the reservoir 2 is a bracket 7 having apintle- 8 which forms a pivot of LIQUID-FEEDING DEVICE.

Serial No. 131,929.

an oscillating member 9. This member has outwardly extending arms 10 to which is secured a weight 11. The member 9 has a channel 12, in the present instance in the form of a longitudinal, as well as a trans versely curved trough. The longitudinal curvature of the channel is substantially concentric with the pintle 8, the function of which will be hereinafter explained. 11 capillary means such as a wick 13 composed of a plurality of strands'ot' wool, or other similar material, is securedat 14 to one end of the channel 12 and disposed longitudinally therein, while the other end is passed through a hole 15 in the channel and looped around the pintle 8. The free ends of the wick 13 extend downwardly and rest in a sump 16 in the bottom 6 of the reservoir 2. One or more of the ends of the wick may be held in position in the sump by a depending lug 17 on the bracket 7.

An open chamber 18 is formed by walls 19 uprising from the bottom 6 to the level of the top of the body, which chamber has an outlet 20 leading into a tubular sight-glass 21, secured in position by a bushing 22 threaded in a support 23 spaced from the bottom 6. This bushing 22 is screw-threaded at 24 to receive a pipe connection (not shown) through which the liquid lubricant enters and is directed to parts of the machine desired to be lubricated.

The member 9 is actuated by means of a piston 25 mounted to reciprocate in a cylinder 26, vertically disposed in the reservoir 2 and secured to the bottom 6. The lower end of the'piston 25 is provided with a valve 27 which is arranged to coact with a seat 28 located at the top of a'passage 29 in a stem 30-, depending; from the bottom of the body. This stem 30 is provided with screw threads 81, by which the device may be connected with a fluid actuated means (not shown) of any well known or approved form.' The upper end 32 ofthe piston is arranged to receive a link 33 which is connected to a pin 34, carried by cars 35 extending outwardly from the member 9. The upper end of the piston 25 is also provided with a cap 36 which coacts with the outer walls of the cylinder 26 and serves as a guard to prevent oil passing from the reservoir into the cyli-nder 26 when the device is in its operative position. In the inoperative position of the member 9, the outer end o'lithechannel 12 is disposed so as to overhang the chamber 18 above the level of the liquid in the reservoir, as clearly shown inFig. 3. When the member is in its operative position a portion ofthe channel12 will extend through the chamber 18 and its outlet 20, so that the outer end thereof will be disposed within the sight-glass 21 and below the level of the liquid in the reservoinas "shownin Fig. 4.

The inoperative position of the elements of the device is shown in Figs. 1, 2, 3and 5, and it is to be understood that the parts of the machine (not shown) to belubricated are at rest. hen the parts of the machine are'set in motion, it is to beassumed that,

the fluid actuated means (not shown) is also energized and exerts a suction throughthe passage 29 in the stem 30, which suction draws the piston downwardly so that the valve 27 will rest uponits seat 28, as shown in Fig. 6." Thls downward. movement of the piston 25, through thelink 33 and ears 35, rocks the member 9 on the p'intleS and causes the channel 12 with the wick 13therein to enter the chamber 18 and sight-glass 21, as shown in Fig. 4. In this positiom'by reason of capillary attraction, the liquid' lubricant will. flow upwardly from the reservoir through the wick 13, thence along the channel and downwardly until it drips off the lower end of the wick and channel through thesight-glass 21 and into the connection (not shown) where it is directed by any well known or approved. means for carrying the liquid lubricant to the parts of the machine to be lubricated. When the suction is broken, the piston 25 willbe released and, by reason of the weight 11 on the arms 10 overbalaneing the weight oi the piston and adjacent elements, the member 9 will be again caused to. rock, which; movement of the member causes the link 33, through the ears 35 on the member to lift the piston 25 so that the device will be rendered inoperative. In this position the outer'end of the channel 12 with its wick 13 therein will be lifted above the level liquid lubricant in the reservoir and thecapillary attraction of the wick arrested.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing frol'n the spirit and scope of my invcntiong hence, I do not intend to be limited to the particular embodiment herein shown and described, but
